Current Improvement Projects

Park Avenue Sewer Augmentation project 

The Pima County Regional Wastewater Reclamation Department (RWRD) and its contractor Borderland Construction, began construction of the Park Avenue Sewer (PAS) Augmentation project on May 30, 2017. The PAS Augmentation project will upgrade a portion of the existing sewer to address capacity limitations and install a new 10-inch sewer interceptor line along Drexel Road from Park Avenue to First Avenue. This is part of a larger project that will also augment the Old Nogales Interceptor (ONI) from 36th Street to Old Vail Road and construct the new Aerospace Corridor (ASC) sewer along Old Vail Road from Nogales Highway to the Wilmot Prison.

Southeast Interceptor Sewer Augmentation (SEI) project

The Pima County Regional Wastewater Reclamation Department (RWRD) and its contractor, KE&G Construction, Inc., will soon begin constructing the Southeast Interceptor Sewer Augmentation (SEI) project, a 2.6 mile project, which extends south from Simpson to 36th Streets and east along 36th Street between 7th and Euclid Avenues. The SEI project will upgrade a portion of the existing SEI to address capacity limitations between Simpson and 36th Streets. Ultimately wastewater flows from a new Old Nogales Highway interceptor, including developments along the planned Aerospace Corridor, will also be conveyed by the SEI project.

The North Rillito Interceptor (NRI) project

The North Rillito Interceptor (NRI) project was completed in April of 2017. The NRI is a 10-mile, large diameter pipeline that transports wastewater from the City's far east side in the Woodland Road and Bear Canyon area, along the north bank of the Tanque Verde Creek and Rillito River, to the Ina Road Wastewater Treatment Facility -- which serves a major portion of northern and eastern Tucson.

22nd Street Sewer Augmentation

The award winning, 22nd Street Sewer Augmentation project extended from Alvernon Way to Swan Road. This work was necessary because the existing pipe was at or near its maximum flow capacity. This project increased sewer volume and improved the lifespan of the sewer infrastructure in the area.
